It may seem counterintuitive to look to the rock beneath the ice of Antarctica to calculate how much ice will melt and how fast sea levels will rise due to climate change, but for the first time, ...

Deep beneath the surface of our planet lies the Earth’s core, a solid ball of iron under crushing pressure. Now, however, scientists conducting laboratory experiments have found evidence suggesting it ...

About 1,800 miles beneath the surface, Earth’s internal structure changes abruptly where the solid rock of the mantle meets the swirling molten iron of the outer core. But the boundary between the ...

Scientists may finally be closing in on the origins of two colossal, mysterious structures buried nearly 1,800 miles inside Earth—hidden formations that have puzzled researchers for decades. New ...

The Earth’s inner core, a solid sphere predominantly composed of iron and nickel, occupies a central role in our planet’s evolution and geodynamo processes. Although hidden beneath thousands of ...

Picture all of Earth’s oceans, which cover about 70% of the planet and are mostly made of hydrogen. Now multiply that by nine. That may be the amount of hydrogen in Earth’s core, possibly making it ...

The Committee on Solid Earth Geophysics serves as the focal point for community discussion and community-agency interaction on issues related to the structure, dynamics, and evolution of the Earth.

The circular formation, highlighted by the space agency’s Earth Observatory, features rings made of sedimentary and igneous ...
